It replaces the original OEM pack when the existing battery no longer holds charge or has swollen. Dimensions are 87.10 × 64.82 × 4.80mm — measure your current cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGS270 fit confirmation:\u003c\/strong\u003e\n    The GS270 uses a single-cell Li-Polymer pack on a 3.85V nominal rail. This cell matches that voltage, the original connector pinout, and the BMS communication protocol the GS270's charge IC expects. No other Gigaset model in the GS2xx range uses this exact cell footprint.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the GS270 platform. The BMS handshake completed on the first cycle, the fuel gauge IC accepted the new cell without lockout, and charge current ramped normally through CC-CV transition.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    Disable fast charging for the first complete discharge-charge cycle after installation. The GS270's fuel gauge IC is calibrated to the old cell's discharge curve. Running one full slow cycle gives the coulomb counter time to map the new cell before fast-charge current is applied to an uncalibrated state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the GS270 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe GS270's fuel gauge IC stores a learned discharge curve from the original cell. A new cell with different internal resistance will hit the voltage cliff at a different state of charge than the old curve predicts. When the modem transmits or the screen brightness spikes, current draw pulls the cell voltage below the shutdown threshold before the percentage reads zero. The fix is one full discharge-charge cycle with fast charging off — this forces the coulomb counter to relearn the actual cutoff voltage of the new cell. After that cycle, the reported percentage and the real remaining capacity will align.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGS270 not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge in storage. If the pack drops below approximately 2.5V per cell, the BMS enters a lockout state to prevent thermal damage and will refuse to deliver current to the device. The GS270 will show no response — no boot logo, no charging animation. Connect the phone to a wall adapter rated at least 5V\/1A and leave it for 20–30 minutes without pressing the power button; the charge IC will trickle current into the cell until voltage climbs back above the BMS re-enable threshold, typically around 3.0V, at which point the phone will boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392018284634,"sku":"BWCS-GMS270SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392018317402,"sku":"BWCS-GMS270SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392018350170,"sku":"BWCS-GMS270SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMS270SL-1.webp?v=1779142944","url":"https:\/\/batteryweb.com\/products\/gigaset-gs270-replacement-battery-385v-4750mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
